As of January 1, 2025, major changes to HVAC refrigerant regulations are now officially in effect, and they’re already impacting homeowners across the country. These new rules phase out high-global warming potential (GWP) refrigerants like R-410A in favor of more climate-friendly alternatives such as R-454B and R-32.
At Top Flight Heating & Air, we want homeowners in Delaware and surrounding areas to feel informed – not blindsided – about what these updates mean for your current HVAC system, your repair costs, and any upcoming replacements.
Why Did Refrigerant Rules Change in 2025?
The Environmental Protection Agency (EPA), as part of the American Innovation Manufacturing (AIM) Act, is working to reduce the use of hydrofluorocarbons (HFCs) – the class of refrigerants responsible for significant greenhouse gas emissions.
Refrigerants like R-410A have a high GWP, meaning they trap heat in the atmosphere if released during leaks or improper disposal. New refrigerants like R-454B and R-32 offer the same cooling performance with far less environmental impact – up to 75% lower GWP in some cases.
These changes also align with global efforts to slow climate change and improve HVAC system efficiency.
What Does This Mean for Homeowners?
Your Current HVAC System Will Still Work
If your system runs on R-410A, you don’t need to panic. You can still use it, and certified technicians like ours can continue servicing it for the foreseeable future.
Repairs May Become More Expensive
Because R-410A is being phased out, it will become harder to source and more expensive over time. If your system needs frequent recharging or major refrigerant-based repairs, the cost will likely rise. For older systems nearing the 10-15 year mark, replacement may be more cost-effective long-term.
All New Systems Use Low-GWP Refrigerants
Any HVAC system manufactured and sold in 2025 or later must comply with the new refrigerant guidelines. That means if you’re installing a new unit this year, it will likely come with R-454B or R-32, along with updated components designed to handle these refrigerants safely and effectively.
Should You Upgrade Your HVAC System?
If your system is in good shape, there’s no need to rush. But if it’s older, inefficient, or requires frequent repairs, now is a smart time to plan ahead. Upgrading to a modern system ensures:
- Compliance with current EPA standards
- Better energy efficiency and lower utility bills
- Access to replacement parts and refrigerants for years to come

What Homeowners Should Do Now
If you haven’t already, here’s how to stay ahead of the refrigerant transition:
- Schedule an HVAC inspection to assess the age, condition, and refrigeration type of your current system.
- Talk to a certified technician about whether a refrigerant retrofit or full system upgrade makes more financial and environmental sense for your household.
- Be aware of installation requirements. New refrigerants are mildly flammable and require systems designed with safety enhancements – so don’t just trust anyone with the install.
